The purpose of this study was to evaluate the solubility, disintegration and film
thickness of twenty-five commercially available cements-zinc phosphate (AD, AS, DH,
FZ, GCB, HC, HZ, LZ, LMZ, SC and TZ), polycarboxylate (DA, DR, GCC, HPC, LC, PF,
SCB and SU) and glass ionomer (HB and 05) cements used in Korea.
These tests were performed according to the modified methods of KDA Specification
No. 1, 2, ISO 1566, 4104, and ANSI/ADA Specification No.8, 61.
The following results were obtained :
1. The solubility of the glass ionomer cements was higher than that of the zinc
phosphate and the polycarboxylate cements.
2. The film thickness of the zinc phosphate cements was slightly higher than that of
the polycarboxylate and the glass ionomer cements.
3. The solubility and the disintegration of the glass ionomer cements showed
considerable differences according to the products.
